Buckstix I have an old RCBS booklet containing an article by Jack O'Connor about his safaris to Africa including the one with Fred Huntington. I am away from home at the moment so cannot check on the details of the article but from memory there is a photo of Fred posing with a lion he took with his 416 Rigby. In another article in the same booklet Jack gives details of the loadings he and Fred used in their 416's. They turned the belts off 378 Weatherby Magnum cases to form 416 cases and got 416 bullets from Barnes if my memory serves me correct. I will post scans of the articles when back home on Sunday.
